Tamborine Mountain Weekly Bird Observations

Birds observed by competent householders in the vicinity of their house yards/gardens on Tamborine mountain At 137, Sierra Dr. (-27.918;153.170) the volume surveyed is about 50m X 50m X 100m high (i.e. about 0.5 cu. ha.). Birds are observed at irregular intervals, counted if there are more than one, and recorded on the bird sheet beside the appropriate bird name and atlas number, in the weekly column dated the following Sunday. Thus Monday starts a new column. Other observers recorded similarly although their observational volume may have been a little different. Bird sheets have 26 columns (half a year). When full they are transcribed to a computer format designed by Stephen Sims, stored by the observers, and transferred by USB memory device to a master copy held by Stephen Sims.
